The previous Assistant tab had a drop down for lens type, plus focal
length and crop factor, all in the space next to the first button.
This was exposing deep photo techno stuff to first-time users that in
reality would be auto-detected (if the focal length can't be detected
in the EXIF metadata, you still get a pop-up asking for it as before).
With the split button, the lens type options appear only if you click
on the pull down arrow - and the first item is labelled as default, so
I *hope* anyone exploring these will be gently made aware only that
there are other possibilities.

The problem is that: although using the XYZ mosaic parameters to
stitch scans is conceptually the right way to do it (because sometimes
your 'scans' are from a mounted camera or microscope and need lens
correction); the simple way of doing it that abuses the lens d&e
parameters is more stable and works perfectly for flat-bed scanners.
You can read the labels as 'scanned images' and 'scanned images using
cryptic other stuff', which is about right.
What I like about this new framework is you can try it, undo, try
something else etc... Before, these assistant scripts were difficult

It is a photo technique where you shoot bracketed exposures and
reconstruct a normal (non HDR) image that uses the lowest noise data
for the dark areas of the image. It gives spookily high quality
results, especially if you are printing. You need a tripod and a
static scene, so it isn't an everyday technique:

The buttons have the same tooltips as before ("Load a series of
images"), there are no tooltips for the individual menu entries.
